Good morning, commuters! We’re in for another warm and humid day, with some possible showers heading our way later today, according to the Capital Weather Gang.

The biggest change to this week’s commute is happening on New York Avenue, where reconstruction of the bridge just east of the intersection with Florida Avenue began Monday. The road’s six lanes were cut down to four, with each direction losing one lane.

I checked out the area during Monday morning’s rush hour, and it didn’t appear to cause any delays or problems. But officials warned that traffic may have been light due to the holiday, so if you travel that way today and in the future you might run into some delays.

The District Department of Transportation says to expect delays of 15 to 30 minutes, but they also gave drivers some ways to avoid this spot: Commuters can try some alternate routes or apply to a program essentially paying people to stay away.

We’ll be rounding up any headaches, issues or problems we hear about on the roads this morning. Let us know anything you see out there — tell us in the comments below or via Twitter (@DrGridlock).

So far: I-95 North is seeing some delays. The roadway is already pretty backed up in Woodbridge and again approaching the Fairfax County Parkway.
